What should I know about battery backup and safety upgrades in Litherland?

A battery backup unit lets the door run for a limited number of cycles when the mains power is off.
After fitting, the door is tested to check it stops and reverses as it should with the new devices.
We check your motor and control box are compatible with the upgrade before the visit is booked, not on the day.
Photocells mounted either side of the opening stop the door closing while anything is breaking the beam.

Rules that apply in Litherland

Powered door safety

Every powered door we fit is commissioned with force testing to BS EN 12453 and handed over with a Declaration of Conformity and UKCA or CE marking, as the Supply of Machinery (Safety) Regulations 2008 require.

Electrics

An electric door needs a power supply near the roller box. Electrical work must meet BS 7671, and in England some domestic electrical work is notifiable under Part P, so it is done by a registered competent person or signed off by building control.

Battery backup and safety upgrades in Litherland: questions

How much is a visit in Litherland?

Prices for battery backup and safety upgrades start from £99 inc VAT, and the price is agreed before anyone comes out. Any parts not covered by that price are quoted before they are fitted, so you can decide on the spot. The guide prices are the same in Litherland as elsewhere we cover.

Do you repair roller doors you did not fit in Litherland?

Yes. We repair roller garage doors of any make in Litherland and across L21, L22 and L20, where parts are available. If a part is no longer made, we tell you what will fit instead, or price a replacement door if that is the better option.

Will you fix the door on the first visit?

A fault can sometimes be found and put right on the first visit, but we never promise it. If a part needs ordering, we quote for it first, make the door safe where we can, and confirm the return date in writing.

Can I message you a photo of my garage in Litherland?

Yes. Photos of the opening, the inside of the garage above the door and any existing door help us give a more useful guide price for Litherland. Send them by WhatsApp or mention them in your enquiry, and we will reply in writing.

How many times will a battery backup open the door?

It depends on the unit, the motor and the size and weight of the door. A battery backup is designed for a limited number of cycles in a power cut, not for running the door for days. If you need the door after the battery runs down, use the manual override as the manufacturer's instructions describe.

How often should I test the safety edge and photocells?

Test them monthly, following the manufacturer's instructions for your door. The aim is to confirm that the door stops or reverses when the safety edge meets an obstruction, and won't close while the photocell beam is broken. If either test fails, don't keep using the door until it has been checked, and request a visit.
